Witnesses told NBC San Diego that Sanchez, 29, was driving so fast and the impact was so intense that the male victim's leg detached from his body and wound up flying through the back window and onto the trunk of the car.

Sanchez allegedly drove to a neighborhood cul-de-sac before leaving the scene.

Officers found Sanchez a short time later at her home and took her into custody, Oceanside police spokesman Ryan Keim told KFMB.
